Resist lightning/acid I squelch instantly; I rather get rid of clutter than be resistant in the early stages - same with ring of fire/cold resistance.

Regeneration gets used unless I am a halftroll, naturally. Paladins and priests love wisdom, everyone else squelches. Infravision is the mainstay early amulet for non-mages, with a mage I prefer regen.

I guess that makes infravision my favourite weak amulet ?

@AmyBSOD:

"Weak" when compared to later amulets like ESP. Obviously regeneration is better than no amulet.

The thing about regeneration is that it ups the pace of your game tremendously. Beefy characters practically no longer need to rest, which is nice, but it's far more useful for caster characters, who go from regenerating 1SP per every few turns, to regeneration 1SP every single turn.

I had a patch once that made explicit, separate HP regen and SP regen flags. The problem was sorting out the display of the character flags screen; there's just not really any more room for more flags.
